mittaisiin

Mittaisiin is a form sometimes discussed in relation to Finnish verb morphology, but it is not part of standard Finnish grammar. It is not widely attested in contemporary language references and is generally treated as a nonstandard, dialectal, or historical variant rather than a regular, productive form.

In standard Finnish, the conditional mood and passive voice combine in forms such as mitattaisiin (would be measured) or the active conditional forms like mittaisin (I would measure) and mittaisivat (they would measure). The form mittaisiin does not appear in major grammars as a recognized productive form. When it is encountered, it is typically regarded as a misspelling, a regional variant, or a very old-fashioned construction rather than a regular part of modern Finnish usage.

Etymologically, mittaisiin could be imagined as derived from the verb mitata (to measure) with a hypothetical suffix sequence, but there is no authoritative documentation confirming it as a standard or widely used variant. In practice, speakers aiming for correct and clear Finnish would use mitattaisiin or the corresponding active conditional forms.
